rachel drove 260 miles using 12 gallons of gas. at this rate, how many gallons of gas would she need to drive 286 miles?
260 / 12 = 21.67 mpg
286 / 21.67 = 13.2 gallons
i dont know that answer
To solve this problem, we can set up a proportion to find the number of gallons of gas Rachel would need to drive 286 miles.
The given information tells us that Rachel drove 260 miles using 12 gallons of gas. This can be expressed as the ratio:
260 miles / 12 gallons
We can set up a proportion using this ratio:
260 miles / 12 gallons = 286 miles / x gallons
To solve for x, we cross-multiply and solve for x:
260 * x = 286 * 12
Divide both sides by 260 to isolate x:
x = (286 * 12) / 260
Simplifying the right side:
x = 3432 / 260
Dividing:
x ≈ 13.23
Therefore, Rachel would need approximately 13.23 gallons of gas to drive 286 miles at the same rate.
